摘要
本文利用AZ91D镁合金锭作为原料,分别将它们加入不同含量的回炉料进行重熔,分析用回炉料生产的镁合金重熔后的组织和性能。结果表明,镁合金添加不同含量回炉料后,组织和性能遗传程度不同。镁合金在熔化过程中,存在的近程有序的原子集团具有和原料组织结构相同或相近的特性,合金液中的团簇造成了镁合金的遗传性。
Remelt the AZ91D magnesium ingot together with different weight ratio recycled scrap in this experiment. The microstructure and property of remelted magnesium alloy when the recycled scrap is added are discussed. The results indicate that the microstructure and property of remelted magnesium alloy take on heredity with different extent to that of feed materials when the weight ratio of added recycled scrap is different. The characteristic of the short range orderly structure atomic group of magnesium alloy is same as or resemble to that of feed materials in the melting process. Thus the atomic conglobation in alloy liquid results in the heredity of magnesium alloy.
